Andeancistrus platycephalus (Boulenger 1898)

Andeancistrus platycephalus is distinguished from its only congener, A. eschwartzae, by having light gray base color of head and body (vs. black to dark gray), uniformly shaped round white to light blue spots smaller smaller than half naris diameter evenly distributed across head, lateral and dorsal surfaces of body and fin rays (vs. irregularly shaped round to vermiculate yellow-gold spots); and by the presence of enlarged clusters of odontodes (keels) at posteromedial apex of most lateral body plates (vs. absence of odontode clusters) (Ref. 104644).

Dorsal soft rays (total): 8; Analsoft rays: 3

Andeancistrus platycephalus is a species of catfish in the family Loricariidae. It is native to South America, where it occurs in the Zamora River basin, which is part of the upper Marañon River drainage in Ecuador. The species reaches 14.5 cm (5.7 inches) in total length. The species was known as Cordylancistrus platycephalus until a 2015 reclassification, when Nathan K. Lujan, Vanessa Meza-Vargas, and Ramiro Barriga-Salazar constructed the genera Andeancistrus and Transancistrus.
